APPAR-ATUS .Fon UNGUMNIING SILK-FABRICS.

Patented Sept. 25, 1906.

Application filed January 19, 1906. Serial Ila. 296,864.

To all whom it'maz concerm.

Be it known that 1,.PETER CHMID, a citizen of the Swiss Republic, an a resident of Basel, Switzerland, have invented new and useful Improvements gumming Silk Fabrics, of which the following is a full, clear, and exact specification.

This invention relates to an apparatus employed for ungumming or removing the sericin envelop from silk fabrics; and it consists of an apparatus having means whereby the fabric treated is conducted through soaplather or suds in a vertical directionthat is to say, with its breadth directed vertically, so as to insure the contact of the lather with all parts of the fabricand means whereby the movingfabric is shifted to ahori-:

zontal position or with its breadth directed horizontally, so that during the Washing it passes through the washing-water in this way. The suds or soap-lather softens and renders soluble the sericin envelop on the fibers of the fabric.

In the accompanying drawings, which illustrate an embodiment of the invention, Figure 1 is a side elevation,partlyin section, and Fig. 2 a plan .view, of an embodiment of this improved apparatus for ungumming silk tissues or fabrics. Fig. 3 is a section on line X X of Fig. 1.

A represents the operating-tank, designed to receive in its lower part a soapy liquid which can be heated by means of a serpentine pipe f, supplied with steam and provided or not with perforations, according as it is desired to heat by direct contact with steam or simply by conduction. Moreover, this opcrating-tank A contains-in its lower part a perforated serpentine pipe y, su plied with compressed air and through whic air under pressure may be injected into the soapy liquid, if desired, for the purpose of favoring the formation of little soap-bubbles in the upper part of the operating-tank A. a

Close to the operating-tank A is arranged a small chamber A, connecting, the tank A to a larger chamber B, connected itself with a washing-tank C. The chamber A is also provided with a steam-heating pipe f and an air-injecting pipe g v,

The operating-tank A, as well as the intermediate chamber A ,contains' vertical guiderollers 6, adapted to guide the different tissue,

or fabrics to e treated, placed one above another, with their transverse extent or breadth directed vertically. '(In the drawin Apparatuses for Un- 'tion-that is to say, a

tatable tlllglcated cones ings there are indicated, for example, three webs.) The chamber B incloses three rotatable truncated cones (Z, other, over which pass the said three webs or fabrics and the functionof which is to bring the latter from the position with their breadth directed vertically to a position with their breadth directed horizontally that is to say, to turn the fabrics angularly for ninety degrees--in order to enable them to pass from the vertical rollers b of the operating-tankA upon horizontal rollers c of the washing-tank C, which latter simply contains Water and is divided by separatingwalls a into a plurality of compartments j.

The fabrics to be treated are continuously supplied to the chamber A through a slot i, provided in the side wall of said chamber and preferably furnished with two elastic tongues eng'aging' the'opposite sides of the fabrics.

They pass then through the chamber A and by a serpentine way over the vertical rollers b of the operating-tank A above. the soapy liquid contained in the chamber A and tank A and through the steam and soap-lather contained in the upper part of these receptacles, which latter have to be in convenient relation with the outer atmosphere for the urpose, of favoring the formation of soaplhther with the aid of air penetrating from placed one, above anthe outside into said chamber and tank. In

this way the fabrics occupy a vertical posiosition with their breadth directed vertical y .so as to have all their parts in intimate contact with the ascending soap-lather bubbles, and thus to be treated in a very efficient manner, upon they come out of the tank A and enter the chamber A, from which they pass through a slot '2 into the chamber B and upon the ro- (Z and afterward upon an a liary roller (1 twenty degrees to the horizon, and finally 'reach the horizontal rollers 0' of the washingtank 0, into which theypass through the washing liquid contained in the compartments 3'. After having been washed therein they leave the last compartment 1' through a horizontal slot 7 provided in the side wall of the tank 0. During the wholeoperation the fabrics are preferably moved continuously; but they might also be displaced intermittently. Y l

The side walls of the tank A are provided with convenient normally open "apertures y,

arranged at djfierent heights and designed whereinclined at about 1 to allow the admission oi air for favoring the formation of the soap-bubbles.

What l claim is 1. An apparatus for the purpose specified, having an operating-tank with means for producing soap-lather in. its upper part and guide members arranged to guide the fabrics to be treated therein through the soap-lather in a position. with their breadth directed vertically for the purpose of allowing intimate content of the soap'lather with all the parts of the fabrics, at washing-tenlt with guide members arranged to guide the fabrics treated in said operating-tank through waterbath ir a position with their breadth directed horiz iontally, and means between said two tonlrs for turning the fabrics from their vertical position in the operatingtank to their horizontal position in the washing-tank, substantially as set forth.

2. An apparatus for the purpose specified,

having an operating-tenk with means for producing soap-lather in its u or part, and vertical rollers designed to guid e the fabrics to be treated therein through the soap-lather in. a vertical. position, a washing-tank with horizontal rollers designed to guide the fabrics treated in said operatingtank through a water-bath in a horizontal position, and means between said two tanks for turning the fabrics from their vertical position in the operating-tank to their horizontal position in the washing-tank, substantially as set forth.

3. An apparatus for the purpose specified, having an operating-tank with means for producing soap-lather in its upper part, and vertical rollers designed to guide the tissues to be treated therein through the soap-lather in a Vertical position, a washingtank with horizontal rollers designed to guide the tissues treated in said operatingtank through a water-bath in a horizontal position, and one or more truncated cones in a chamber between said two tanks adapted to turn the tissues from their vertical position in the operating-tank to their horizontal position in the washing-tank, sul'lstantially as set forth.

4. An apparatus for the purpose specified, having an operating-tank with means for producing soap-lather in its upper part and with vertical rollers designed to guide the fabrice to be treated therein through the soaplather in a' vertical position, a washing-tank with horizontal rollers designed to guide the ,tabrics treated in said operatin tank through a water-bath in a horizontal position, and means between said two tanks for turning the fabrics from their vertical. position in the operating-tank to their horizontal position in the washing-tank, the said operatingtank comprising a large and wide chamber A and a narrow and small chamber A substantially as set forth.

In witness whereof I have hereunto signed my name, this 9th day of January, 1906, in the presence of two subscribing witnesses.
